Abstract

Purpose Our study aimed to evaluate the acceptability, adverse effects and continuation rates among adolescents who accepted the etonogestrel (ENG) subdermal implant and compared to adolescents who chose other methods during the immediate postpartum period before hospital discharge, with one year follow-up up. Materials and methods We conducted a cohort non-randomised study at the Women's Hospital, University of Campinas. All women up to 19 years of age, who gave birth at the hospital between July 2019 and April 2020, were invited to participate and were offered the ENG-implant or the routine contraceptive methods. They were followed for one year postpartum. Results We included 100 teenagers and 72 accepted the ENG-implant. Students are more likely to accept the ENG-implant than non-students (PR: 1.25 [95%CI 0.99-1.59]). Up to one year of follow-up, survival analysis showed that the time of adherence to the method was longer for the ENG-implant users (p = 0.0049). More than 90% of the adolescents were satisfied with the implant; however, five requested early removal due to menstrual irregularity and local discomfort. Conclusion Provision ENG-implant for adolescents in the immediate postpartum demonstrated high acceptance and ensured effective contraception. After one year, most of them were satisfied, with a high continuation rate and without unplanned pregnancies. (AU)
